The effect of C3G on lymphocyte subtypes and cytokine secretion in CIA rats using flow cytometry. a Proportion of lymphocyte subtypes to total lymphocytes in rat peripheral blood (PB). b Correlation of CD38+ natural killer (NK) cell proportion to Treg proportion in rat PB. c Cytokine concentration in rat PB. d Proportion of lymphocyte subtypes to total lymphocytes in rat synovial fluid (SF). e Correlation analysis of CD38+ NK cell proportion to Treg cell proportion in rat SF. f Cytokine concentration in rat SF. * indicates p < 0.05, **p < 0.01, and ***p < 0.001
